# Mapstruct fluent extensions generator

[![Build](https://github.com/driver733/mapstruct-fluent/workflows/Build/badge.svg?branch=master)](https://github.com/driver733/mapstruct-fluent/actions?query=workflow%3ABuild+branch%3Amaster)

[![semantic-release](https://img.shields.io/badge/%20%20%F0%9F%93%A6%F0%9F%9A%80-semantic--release-e10079.svg)](https://github.com/driver733/mapstruct-fluent/actions?query=workflow%3ARelease)

[![Licence](https://img.shields.io/github/license/driver733/mapstruct-fluent)](https://github.com/driver733/mapstruct-fluent/blob/master/LICENSE)

This project provides a generator of [fluent](https://en.wikipedia.org/wiki/Fluent_interface) [extension functions](https://kotlinlang.org/docs/reference/extensions.html) for [mapstruct](https://github.com/mapstruct/mapstruct) [mappers](https://mapstruct.org/documentation/dev/reference/html/#defining-mapper).

### Examples

#### [Extension method for the mappers' factory](examples/example/src/test/kotlin/com/driver733/mapstructfluent/EmployeeMapperTest.kt)

```kotlin
data class EmployeeModel(val firstName: String? = null)
data class EmployeeView(val firstName: String? = null)
```

```kotlin
@Mapper
abstract class EmployeeMapper {
abstract fun toEmployeeView(employeeModel: EmployeeModel): EmployeeView
}
```

```kotlin
val employee = EmployeeView("Alex")
employee.toEmployeeView() == Mappers.getMapper(EmployeeMapper::class.java).toEmployeeView(employee)
```

#### [Extension method for the mapper's Spring bean](examples/example-spring/src/test/kotlin/com/driver733/mapstructfluent/EmployeeMapperTest.kt)

```kotlin
data class EmployeeModel(val firstName: String? = null)
data class EmployeeView(val firstName: String? = null)
```
```kotlin
@Mapper(componentmodel = "spring")
abstract class EmployeeMapper {
abstract fun toEmployeeView(employeeModel: EmployeeModel): EmployeeView
}
```

Calling the generated extension function
```kotlin
@Service
class Service {
fun a() {
val model = EmployeeModel("Alex")
val view = employee.toEmployeeView()
}
}
```

is the same as manually using the mapper's Spring bean
```kotlin
@Service
class Service(
private val mapper: EmployeeMapper
) {
fun a() {
val model = EmployeeModel("Alex")
val view = mapper.toEmployeeView(employee)
}
}
```
